Tunnel TX50-19CM, driven southwards from the exploration ramp along exploration line 19 on level 50m, has intercepted:
shredders offer another compelling advantage - bulk reduction.
The vein can be traced over a length of 114 meters (375 feet) in crosscuts
and drill holes, and remains open along strike to the north and south.
saws were not limited to a subset of the lengths) explains much of the difference in cutting efficiency.
Today, though strip-cut models are still available, the trend is toward particle-cut and crosscut
Rib channel sampling in the A crosscut
The continuity of the Roberto Est zone was confirmed up to line 65+50E by hole ELE-05-81, which crosscut
an intersection grading 5.
Since the commencement of the North Porvenir development program in mid-June to the end of December 2004, a total of 1160 m of underground development was completed, including 410 m of new access ramp, a 161 m ventilation raise, eleven crosscuts
into the vein totalling 141 m, two sill levels totalling 135 m and related underground workings.
Many drill holes were done by these companies as well as the completion of a 243-meter vertical production shaft and development of galleries and crosscuts
Mineralized material, taken from the crosscuts
during development, has been stockpiled at the surface.
The decline is currently about 350 metres in length and the second of three planned crosscuts
to expose and access the mineralized zones is nearly complete.
However, scattered crosscuts
driven across the main vein were 8.
From 147m to 365m the hole intersected polymict, potassic altered diorite breccia with a variable chlorite overprint, which crosscuts
the stockworked diorite breccia.
There are approximately 25km of underground workings reported in the Los Azules mine, including three shafts, drifts up to 2km long, crosscuts
, raises and stopes, all on several different levels.
will be driven approximately every 40 metres and detailed underground diamond drilling to locate emerald-bearing veins will be initiated.
